The objective of the work reported here was to determine changes in the moisture content, firmness characteristics, color attributes and NIR absorbance of two carrot cultivars during storage. There was a definite loss in the moisture content that caused changes in the firmness. This result shows that carrot firmness is very sensitive to the moisture content. The firmness — especially the cutting force — is a good characteristic for predicting changes in carrot moisture content during storage. The color characteristics — a* and b* — showed a slight change in the function of the moisture content. However, these color characteristics are suitable for distinguishing the phloem and xylem parts of carrot cultivars. There were not found definite changes in the NIR absorbance as the function of the moisture content. Consequently, the specific cutting force and the impact stiffness coefficient are good characteristics of the carrot moisture content and the mass reduction during storage under non-ideal conditions.

Iron-based alloy GH2132 is a kind of difficult-to-machine material. In this study, the experiments were processed to research the effect of feed per tooth, axial cutting depth and radial cutting depth on milling force. Variance analysis was made on the three factors. The results reveal that axial cutting depth affects milling force significantly, followed by feed per tooth and radial cutting depth has little influence on it. Two types of empirical model of milling force were established by the result of orthogonal experiment and multiple linear regression analysis. It was verified that both (hm, ap) model and (hm, ap, ae) model had good prediction accuracy compared with the experimental data. By calculating specific cutting force using the (hm, ap) model, a modified coefficient of the specific cutting force for 1mm2 chip cross section was proposed. The study would provide guidance to improve the machining precision and machining efficiency of high temperature alloy materials.

This paper presents the results of the experiments which aimed to determine the value of the specific cutting force (SCF) during longitudinal turning of sintered alloy Inconel PWA. The analysis of the influence of cutting speed on the value of SCF was carried out. Taguchi L9 (2)3 orthogonal array has been applied for experimental design. S/N ratio and ANOVA analyses were performed to identify significant parameters influencing specific cutting force. The analysis presents the method that reduces the cutting power during turning of sintered nickel alloy.

The grinding process can be considered as micro-cutting processes with irregular abrasive grains on the surface of grinding wheel. Single grain cutting simulation of AISI D2 steel with a wide range of cutting parameters is carried out with AdvantEdgeTM. The effect of cutting parameters on cutting force, chip formation, material removal rate, and derived parameters such as the specific cutting force, critical depth of cut and shear angle is analyzed. The formation of chip, side burr and side flow is observed in the cutting zone. Material removal rate increases with the increase of depth of cut and cutting speed. Specific cutting force decreases with the increase of depth of cut resulting in size effect. The shear angle increases as the depth of cut and cutting speed increase. This factorial analysis of single grain cutting is adopted to facilitate the calculation of force consumption for each single abrasive grain in the grinding zone.
